The global head of mergers and acquisitions at Deutsche Bank has handed in his resignation after more than a decade at the bank, which had already been braced for tomorrow's exit of group co-chief executive Anshu Jain, a former head of its investment banking arm.

Henrik Aslaksen, who has worked for Deutsche Bank since 2002 and twice appeared in Financial News's annual pick of the 100 Most Influential people in European capital markets - in 2012 and 2013 - is to leave in a "shock" move, according to a person familiar with the move, who said it is expected to be announced to staff on Monday.
